> I am running OASIS spec compliance test in another hosting environment. When I run the test that includs DTD definition in composite, (e.g. JCA_9016), the parser in my hosting environement will throw the following exception.
> javax.xml.stream.XMLStreamException: A non-whitespace event found while calling nextTag.
>                      ... parser code
> 	at org.apache.tuscany.sca.contribution.processor.ExtensibleStAXArtifactProcessor.read(ExtensibleStAXArtifactProcessor.java:155)
> To bypass the issue, I commented the ExtensibleStAXArtifactProcessor code with mine new code:
> //        if (event == XMLStreamConstants.START_DOCUMENT) {
> //            source.nextTag();
> //        }
>         if (event == XMLStreamConstants.START_DOCUMENT) {
>         	while (source.next() != XMLStreamReader.START_ELEMENT);
>         }         
> Here is the java doc for the nextTag:
> nextTag
> public int nextTag()
>             throws XMLStreamExceptionSkips any insignificant events (COMMENT and PROCESSING_INSTRUCTION) until a START_ELEMENT or END_ELEMENT is reached. If other than space characters are encountered, an exception is thrown. This method should be used when processing element-only content because the parser is not able to recognize ignorable whitespace if then DTD is missing or not interpreted. 
> Returns:
> the event type of the element read 
> Throws: 
> XMLStreamException - if the current event is not white space
> Thanks.
